rosrrrvn OILING- DEVICE FOR BEARINGS.

Specification of Letters Patent. Patented Jan. 16, 1912.

Application filed July 29, 1907. Serial No. 386,051.

To all whom it may concern:

Be it known that I, WILLIAM S. SUTTON,

' a citizen of the United States, residing at Madison, county 'of Dane, State of Wisconsm, have invented certain new anduseful. Improvements in Positive Oiling Devices for Bearings, of which the following is a specification.

.My invention relates to a new device for positively oiling bearings, and has for its 7 object a novel construction and arrangement of parts. a y The various forms of novelty which char acterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification.

For a better understanding of my invention, reference may be had to the following description taken in connection with the accompanying, drawing in whic'h Figures 1 and 2 show sections through the centerline of a ball thrust bearing provided with my inventiony Fig. 1 showing the position of the actuating parts at one limit ofmovement of the pump plunger; and Fig.

- 2 the position of these parts. at the other limit of movement. I

The corresponding parts in the two figures are indicated by the same numerals.

In the particular form in which I have illustrated my invention, 1 have shown a pump, consisting of a disk or plunger at the lower part of the ball thrust bearing actuated by a rod which extends to the upper part of the bearing. Motion is imparted to this rod by means of a member carried by the shaft, another member moving transversely thereto and operatively connected to the rod, and a device rolling between these members. I

l is the frame or bonnet supporting the bearing.

2 is the bonnet sleeve which supports the bronze bearing sleeve 3.

4; is a journal sleeve running in the hearing sleeve 3 and attached to the shaft 12.- The shaft bearing illustrated has the lower ball race 7, provided with a race to receive the balls 8, above which balls is the upper ball race 9. The upper ball race 9 is provided with a bearing or track for the balls and concaved on its upper side to receive a correspondingly conve'xed bearing block 10, the

- mutual action between these two members distributing the strain equally over the whole ball race. The upper end of the shaft is threaded to receive a nut or otherwise provlded with means whereby the Weight is sustained by the ball races which are supported by a shim 6 and the bearing sleeve 3. A cap 11 is placed over the bearing to protect it from dust and prevent oil from being thrown out of the hearing. A suitable o'il chamber 5 with suitable openings and means for holding is also provided at the bottom of'the bearing. I

The shim 6 supporting the ball race 7 is provided with upwardly extending columns connected with a recessed ring 22 which supports an oscillating ball race 14. shaft 12 carries the disk or ball race 15 which also acts as a washerfor supporting in position the self-adjusting step 10 and with respect to which the ball race 14 moves v transversely. Between this race and the race [4 a ball 16 runs. The race 14 is in contact with the rod 26, at its upper end, which rod actuates the pump. The lower end is in contact with the bracket 24, and the rod is pressed upward by it. The bracket 24 is fastened to the disk or pump plunger 13 by screws as shown, and permits the rods to pass down in a vertical position, which is preferable for mechanical reasons to having the rod inclined and resting on the upper side of the disk. The retaining ring 1.7 is narrower at one part than the other, which enables the disk 13 to assume a position which will admit of a slight oscillating motion. The disk 13 is pressed upward against the retaining ring by suitable means, such as by the springs 27, shown in dotted lines on the drawing. To insure free inlet of oil after the disk has been depressed, the disk may have a check valve 25.

In order to avoid any noise which might result from the ball race 14 vibrating in contact with the recessed ring 22, a leather or other suitable washer 21 is provided between the ball race and ring. To insure a slight pressure at the point in the ball race where the ball might be inactive a small spring 20 is inserted under the ball race 14. This ball race is retained in position at one point 011 its periphery by a small screw stud 23 which is placed diametrically opposite the connection to the pump, that is, diametrically opposite the rod 26.

' The oil tube 19 communicates with the oil chamber 5, through the ball check valve 18. The operationof my device is shown by the drawing. In Fig. 1 the ball 16 is in the extreme position of the race 14, where the disk 13 is pressed upward against the retaining ring 17, as there is no downward pressure on the rod 26. The check valve 25 has just closed, oil having flowed through it and filled the oil chamber 5. As the shaft rotates and the upper race 15 with it, the ballmoves also and the race 14 is gradually pressed downward, exerting a pressure on 5 the rod 26, which pressure .is communicated to the disk 13 through the bracket 24. As this disk starts downward the check valve closes due to the pressure on its under side, the ball valve 18 opens due to the pressure, and oil is pumped up through the oil tube 19, through the hole at the top of the tube, on to the surface to be lubricated. This continues until the ball 16 reaches the other extreme position of the race shown in Fig. 2. When the ball has passed this position and approaches the position in Fig. 1 again, the spring pressure on the disk grad ually, forces it and the rod and ball race 14 upward, the pressure inthe oil chamber 5 is ao-relased, the check valve 25 opens and allows the oil to flow into the oil chamber 5, and the ball valve 18 closes.

A preferred design of the device is shown in the drawings, but it is evident that the parts of the device may be given other forms without departing from the s irit of my invention. It may also be use with other forms of bearings than the ball bearing shown.

What I claim as new and desire to secure by Letters Patent of the United States, is,-
